Abstract: Abstract PolyPOSS-imide membranes are promising for separating H2 from larger molecules (CO2, N2, CH4) at temperatures up to 300 °C. Their fabrication involves two steps: interfacial polymerization of POSS and 6FDA, followed by thermal imidization. This… read more here.

DOI: 10.1021/acs.organomet.8b00347
Abstract: The postmodification approach allows convenient access to charge-tagged ammonium-functionalized bis(1,2,4-triazolin-5-ylidene)palladium(II) complexes even when the respective azolium salts are elusive. Bromo-functionalized 1,2,4-triazolium salts were first metalated to form the respective bromo-functionalized bis(NHC) complexes trans-[PdBr2(R-tazy-Br)2] (R =… read more here.

DOI: 10.1021/acsomega.8b02742
Abstract: Novel anion-conductive polymers containing perfluoroalkyl and ammonium-functionalized fluorene groups were synthesized and characterized. The quaternized polymers synthesized using a dimethylaminated fluorene monomer had a well-defined chemical structure in which each fluorenyl group was substituted with… read more here.

DOI: 10.1246/cl.180258
Abstract: Ammonium-functionalized polyhedral oligomeric silsesquioxanes (POSSs) with only cage-like octamers were selectively prepared in high yields (ca. 90%) within relatively short reaction time (7–12 h), when the hydrolytic condensations of 3-aminopropyltrimethoxysilane (APTMS), 3-(2-aminoethylamino)propyltrimethoxysilane (AEAPTMS), and an… read more here.
